Bugfixing for canceling the creation of content.

Needed to re-render the timeline, and rebind the view events to the
proper elements.

Also added requirejs to the deps, in setup for the production mode using
r.js.
Absolute paths for files.

In preparation for using r.js, since it doesn't seem to parse the path
syntax sugar in require.config().
Production mode!

Now building the codebase with r.js.  Still some kinks to iron out -
need to get moment loading properly (not sure why it isn't), and
refining of what gets put into the production folder.
